Battery-box holddown



Nov. 5, 1929 Patents& Nov. 5, 1929 mettaa PATENT OFFICE BBUNO A.POLLAND, OF OMAHA, NEBBASKA :BATTERY-BOX HOLDDOWN I Application filedApril 16, 1928. Serial No. 270,&97.

4 This invention relates to a battery-box holddown, and' has for its`'Principal object to provide a bracket or holder of such constructionthat its metallic parts will be dis With the foregoing objects in Viewthe invention presents a new and useful Construction, combination andarrangement of parts as described hei-ein and claimed, and asillustrated in the accompanyng drawings, it being understood thatchanges may be nade in form, size, proportion and minor details, saidchanges being determined by the scope of the invention as claimed.

In the drawing, Fig. 1 is a perspective View showing the holder Securedto a support. F ig. 2 is a View similar to that shown in Fig. l, abatter'y being added and supported by the holder. Fig. 3is a detailshowin cooperating elements for connecting two o the arms or bands ofthe holder.

Referring now to the drawing for a more particular description, theinvention is shown and described in connection with a support 4; or partof the 'frame of an automobi e', and numeral 5 indicates the' batterybox, these parts being conventional and requiring no description, exceptto state that the acid which' generally exudes from the cells causecorrosion of any metallic parts which are exposed.

The hattery boxes generally used are con structed of vulcanized indiarubber to prevent corrosion but it will be appreciated that stay-downs'or hold downs which grip the top of the box will be exposed to theaction of the acid. These stay-down devices are generally constructed ofattenuated strips to avoid weight and become injured and often aredestroyed byaction of the acid.

It will be seen that in its present embodiment of the invention nometallic parts are disposed 'at the top of the box.

- The nvention consists of an upright supporting-plate 6 approxinatelyof T-shap adaptcd to be Secured to 'sa-id member 4 by any suitablemeans, as by use of keepers 7. The bottom of this plate is provided Witha Sheath &of .angular form in cross-section'.

Numerals 9 indicate a pair of L-shaped bands; They are maintained in ahorizontal postion by hinges 10 which connect one of the ends of eachband to the ends of the arms 11 of the Tshaped plate 6, and on accountof their hinged mounting said bands 9 may have limited horizontalswinging movements.

;Since battery boxes generally have a form rectangular in plan thesheath 8 is of similar form, its upright flange 12 being adapted toengage the sides and its horizontal flange 13 eing adapted to .engagethe bottom ofthe ox. w

I provide fastenng devices which co-operate in operation forpressing thebands 9 firmly against the sides of the box, as the latch 14: which isSecured to one of said bands, and the thumb-catch 15 which is Secured tothe other band '9 said catch being pivotally mounted on its band 9 asindicated at 16, and the latch being ivotally mounted-on said catch asindicatet at 17.

It will be' understood that since the battery boxes are of standard sizethe L-shaped arms and fastening devices may be of such proportions thatthe bands 9 willbe pressed firmly against the sides of the box when thecatch has been moved to position shown in solid lines in Fig. 3, and thesheath is of such proportions that the box will snugly fit therein whenthe box is mo'unted in the bracket.

- In operation, the box may be readily removed. ;The catch ma. be swungoutwardly to the ostion' shown y dotted lines in Fig.

3, whic forcibly moves the bands 9 outwardly from the sides of the box.Since the battery requires frequent replacements this feature will beappreciated. To mount the battery in operative position, it is lowereddown into "the sheath and the catch is then swung so that its handlewill engage the band 9 on which it is mounted, and since this swingingproportions that the battery will project an appreciable distance aboveits upper edge, and since the sheath and bands 9 are disposed atright-eagles to said plate 9 these metallic parts will not be exposed tothe action of the 4 acid at the top of said box and this is an importantfeature. By use of the invention the bands may be of attenuated form sothat they will not add appreciably to the Weight of the vehicle, andsince the sheath closely engages the lower parts of the box its form maybe attennated.

I claim as my invention,--

l. In a battery box holddown, an upright supporting-plate approximatelyof T-shape provided at its lower end 'with ahorizontal sheath forengaging the sides and bottom 'of the battery box, its upper end beingprovided With a pair of L-shaped'bands hingeably mounted on thesupportinglato below the top of said box, and co-operating fasteningelements on said bands for pressing said bands toward each other intoengagement with said box.

2. In a battery box holddown, an upright i supporting-plate of T-shapehaving a sheath at its bottom projecting at right-angles therefrom forengagingthe sides and bottom of the box when seated therein, a pair ofbands hingeably mounted upon and disposed paralled with said sheath forengaging the sides of the box below the top thereof, and means forpressing said bars against the sids" of the box. 4 3. In a battery boxholddown, a supporting-plate approximately of T-shape having a sheathextending at right angles thereto for rcceiving the lower part of thebox, a pair of bands hinged to said plate and disposed above the sheathand approximately parallel with said sheath, and cooperating ;t'asteningdevices for pressing said bands against the sides of said box.

4. In a battery box holddown, an upright supporting-plate engaging oneside and having a lesser height than the height of the box and having asheath extending outwardly from its bottom at right-angles from saidplate for engaging the'sides and bottom of the box, a pair of armsdisposed between the top and bottom of the box parallel with the sheathand hinged to said plate, and co-operating fastening elements mounted onsaid bands for pressing them against said box.

5. In a battery box holddown, an upright metallic supporting-plateapproximately of T-shape having a sheath extending at rightangles fromits lower end for engaging parts rectangular open france carried by thelower end of the plate and at approximately right' angles to the planeof the plate, said frame having horizontal and vertical flanges toreceive the bottom and side portion of the battery, L-shaped bandshinged at one end to the outer ends of the horizontal arms and embracingthe sides and front of the battery be- -low the top thereof, and meansfor opening and closing the hinged bands upon the battery.

In testimony whereof, I have afiixed my signature.

BRUNO A. POLLAND.
